Dataset: Ferric Iron, Hydrogen, and Major Element Quantification in Amphibole Minerals using Raman Spectroscopy and Multivariate Analysis

Supplementary Table 1: Amphibole sample suite localities, previous publications, compositional data (electron microprobe, Mossbauer, and hydrogen extraction line and ion microprobe). Supplementary Table 2: Normalized Raman spectra (50-4250 cm-1) of amphibole sample suite. Supplementary Table 3: Actual and predicted compositional data for individual samples within the amphibole sample suite. Supplementary Table 4: Summary of statistical parameters compositional prediction variables of the amphibole mineral suite. Baseline corrected data (AirPLS, smoothness =1000) with the full wavenumber range (50- 4,250 cm-1). Supplementary Table 5: Multivariate partial least squares (PLS) models coefficients for compositional predictions from Raman data. We recommend mirroring data processing to those described within this work for best results.
